Objectives: The aim of this study was to present an overview of the Green Card Clinic, a novel brief intervention service for patients presenting to the emergency department following deliberate self-harm (DSH) or with suicidal ideation, to examine its effectiveness in terms of service utilization, and patient and clinician feedback, and to explore the correlates of repeated DSH.

Method: The aims and structure of the Green Card Clinic are described. We highlight our patient-centred approach involving self-identification of difficulties from a list of problem areas, coupled with tailored intervention strategies. Relevant data are presented and characteristics of repeat DSH patients are compared to the first-episode group.

Results: Between 1998 and 2005, 456 DSH patients were referred to the clinic. Of these, 75% (n = 344) attended the first session, 43% (n = 197) the second session, 26% (n = 117) the third session, and 16% (n = 73) completed a 3–15 month follow-up. Clinic attenders (mean age 31.6 years, 57% female) reported a diverse range of self-identified problems and repeat DSH patients reported worse depression, poorer health-related behaviours, and a greater number of problems than those presenting after first-episode DSH.

Conclusions: The clinic achieved high rates of first session attendance. This may have been attributable to the use of a few specific strategies aimed at increasing compliance, such as the green card, next-day appointments and assertive follow-up of non-attenders. For repeat self-harmers, we advocate an approach aimed at ‘lifestyle change’ rather than based on current psychological stressors. The Green Card Clinic service, involving a range of interventions tailored to meet the multitude of presenting needs, appears to be an acceptable and flexible approach to brief intervention for DSH.
